DTC B1422: Compressor Lock [06/2018 - ]: Description
WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2024 Lexus ES 350, 2024 Lexus ES 250, 2023 Lexus ES 350, 2023 Lexus ES 250, and 2022 Lexus ES 350. However, it is still accessible from the selected car via links, so may be relevant.
The ECM sends the engine speed signal to the air conditioning amplifier assembly via CAN communication.
The air conditioning amplifier assembly reads the difference between compressor speed and engine speed. If the difference becomes excessively large, the air conditioning amplifier assembly determines that the compressor is locked, and turns the magnet clutch assembly off.
